(A) Claudin-4 Western blot for SKOV3 WT, a negative control, and SKOV3 siRNA (claudin-4 silenced). β-Actin was used as a loading control. (B) Junctional (paracellular) resistance (Rb) was compared between SKOV3 WT (wild type) and SKOV3 siRNA (siRNA claudin-4 silenced) cell lines over 7 days in cell culture medium, *P < .05. Cell lines (C) OVCA429 and (D) SKOV3 were treated with increasing amounts of C-CPE (µg/µl), resulting in a dose-dependent decrease in Rb compared to control (cell culture medium only, C-CPE concentration of 0 µg/µl). Bars represent means ± SD. Measurements were repeated four to six times, *P < .05.
